A New Generation of Fiber Optic Oxygen Sensors Based on Luminescence Lifetime
Oxygen measurement is simpler than ever. Just stick a disposable, oxygen-sensitive "spot" to the inside of a flask, beaker, test tube or bottle, and fill the container
with the solution to be tested. Then, on the outside of the glass container, hold the fiber optic wand close to the spot to take a reading. As the spot reacts with oxygen, it gives off light, which is measured with the fiber optic wand. This ingenious system is highly accurate and affordable. Two different units (which use the same operating principles are available: OXY-MINI and OXY-MICRO.
The OXY-MINI system is optimized for process control and biotechnology applications. The

WPI offers a range of biosensors for monitoring nitric oxide, hydrogen peroxide, oxygen and hydrogen sulfide. Specifications for these sensors are detailed below.
The macrosensors are 2mm "wet" sensors. These sensors are installed in a metal "sleeve" that looks like a tiny soda straw.The sleeve has a gas permeable membrane at the tip, and it is filled with an electrolyte. When it is immersed in a solution, the gas in solution (for example, nitric oxide) diffuses through the membrane, and the sensor measures it.
The microsensors are "dry" sensors. Most microsensors monitor nitric oxide, and there is also a hydrogen
